Problems solved by technology

At this time, the surface subsidence has often occurred for a long time, and the diseases caused by the grouting defects have already produced significant economic losses, so the significance of detection at this time is relatively small
In addition, manual detection is easily restricted by on-site conditions, and the detection stability is poor

Embodiment 1

[0022] Embodiment 1; as figure 1 As shown, the device includes a ground penetrating radar 1 , a servo controller 2 , a drive motor and a reducer 3 , a transmission mechanism 4 , a radar acquisition box 5 , a bracket 6 , an assembled track 7 , a pulley 9 and a conveyor belt 10 . The ground penetrating radar 1 is connected to the conveyor belt 10 through the support plate, and the conveyor belt moves along a circle under the traction of the drive motor, the reducer 3 and the transmission mechanism 4, and the motion mode is controlled by the servo controller 2. The ground penetrating radar 1 acquires the radar signal and transmits it to the radar acquisition box 5 through the coaxial cable, and transmits it to the computer in the control room through the network cable for data analysis.

[0023] figure 2 It is the assembled track segment diagram of the present invention. According to the actual detection angle requirements, the number of stages required for the assembled track ...

Abstract

The invention relates to car frame traveling type shield tunnel wall post-grouting detection equipment. The equipment comprises a car frame traveling type automatic transmission device, an air-coupled ground penetrating radar and a wall post-grouting body intelligent processing analysis software. The equipment is integrated by hardware and software, and achieves wall post-grouting layer real-time visual detection in the shield construction process. The car frame traveling type automatic transmission device mainly includes a track, a synchronous belt, a transmission mechanism, a servo extension and drive, and a reducer; by carrying a novel air-coupled radar detection device installed on a shield first section car frame, circumferential detection and grouting body layered visual display are conducted on the shield grouting body with shield driving.

Description

technical field [0001] The invention belongs to the field of post-wall grouting and cavity detection during the construction period of a shield tunnel, and in particular relates to detection equipment for post-wall grouting of a vehicle frame accompanying type shield tunnel. Background technique [0002] In recent years, as the country strengthens investment in infrastructure facilities, my country's transportation construction and unemployment have achieved rapid development, and the construction and research of highway tunnels, especially long tunnels, have also achieved rapid development. At present, my country has become the world's largest tunnel The country with the largest number of projects, the most complex and the fastest developing. Based on the principle of "protecting the head, protecting the tail and grouting" in shield construction, the detection of the grouting thickness behind the shield wall is realized through the development of radar detection equipment. ...
